cluding valvesfand pipes, but preferably it leaves the ittingsprojecting as illustrated.

`The casing is open at levels above the top of the radiator proper forthe discharge of heated air and also at levels below the radiator totake in cool air.- In the cases illus-v `rated the bottom of the casingis open for admission of air, but the admission opening might bearranged at the front or the ends below the ievel of the inlet to theradiator lues.

In 1 there is a front discharge through the upper portion of the frontpanel and in Fig. 3 the discharge is through the top of the casing.

In Fig. 1 the casing has a closed ltop wall 5,-end walls 6 and a frontwall or panel 7 at the upper edge of which is located a perorated plateor grating 8 for emission of the heated air. f

The end walls 6 are provided with oblique slots 9 open at the rear edgeto permit passing of the latter across a projecting pipe such as `theinlet pipe 10. Asiinilar oblique slot at the lower part of theoppositeend Wall accommodates the outlet `pipe 11.

The casing may be long enough to enclose the projecting pipes andfittings. It may also extend clear down to the floor. In fact itsproportions may be variously altered. An illustration of suchmodificationsk is not attempted, since they do not affect the invention.l

According to Fig. ,3 the front panel 7 is closed clear to its upper edgeand the top 12 is perforated to permit the escape of heated air. Y

lt is assumed in the specific cases illuslevel from the wall and iscarried up to the valve 17 which leads to thepinlet pipe 10 of theradiator.

The casing is a unitary transportable structure applicable to theradiator after the latter has been installed and adapted to be supportedby the radiator; so that, vwhen the latter is suspended abovethe flooras indicated, the lower edge of the casing may also clear the floor.

The casin may be simply and economically made of s eet metal, such ascopper, brass or steel, grained to harmonize with the furniture orwoodwork in a room, or painted so as to harmonize with the color of thewall orM decorated 'according Ato any desired scheme.

In applying the leasing to the radiator, nothing more is necessary thanto slip it in place by a downward movement over the top of the radiator.It Vprotects the radiator against injury.-

vThe Murray radiators referred to are generally made of extremely thincopper or other sheet metal which is liable to distortion by a slightblow so that a protective casing is particularly useful with this typeof radiator. The material and method of production make it possible tomanufacture the casing very cheaply. A

The top plate 12, Figs. 3 and 4, has va rear flange 18 bent downsufficiently to embrace the'rear face of the radiator. End flanges 19are bent down to fit against the outer faces of the end'walls G. A frontflange 20 is bent down and preferably-'molded into'a graceful shape tooverlap'thefront panel 7. The end plates' are similarlyflanged and bentover to form stiffening moldings 21. And the lower edge of the frontpanelis formed with a corresponding molding 22. The centre of the frontpanel may be further 'ornamented and stiifened as desired.

The top, ends and front panel are readily stamped out and bent to theflanged and molded shapes described. They arethen assembled in a jig andspot welded or otherwise firmly jointed. The molding at the lower edgeof the panel may be integral with the panel, as in Fig. 4, or a separatestrip welded to the sheet as injFig. 7. The casing is intended to fitfairlyclosely' about the radiator. It should also be held firmly againstdisplacement thereon.

Where a top-discharge of the hot air is permissible, as in the usuallocation immediatel below a window, the casing may rest direct y on topof the radiator, as in Fig. 4. Where a front-discharge of hot air isdesired, Fig. 6, the top has a depending flange 23 at the back, atr thelower edge of which is an angle iron 24, a flange of which projects overthe top of the radiator. The angle iron is secured to the plate 23 andmay extend along the entire length vthereof or may be in slliort lengthslocated at intervals along the p ate.

To prevent longitudinal displacement of the casing with relation to theradiator, the front panel 7 has securedto it near its ends, verticalangles 25 (Fig. 5) whose inwardly projecting flanges bear againsttransverse fins 2 of the radiator. To prevent the lower free edge of thefront panel frombecoming bulged or otherwise distorted in time, it ispreferable to fasten it also to the radiator. This is done by clips,such as are shown in Fig., 7 embracing theedge of the panel and alsoembracing the lower end of a longitudinal web 3 of the radiatingstructure. There may be two of these clips, one at each end of thepanel, or more, if the panel be of consi lerable length.

' The clip is of spring metal with a hollow centralfportion 26 adaptedto embrace the edges of the parts. An inner flange 27 facilitatesintroducing it over the web 3. An outer flange 28 is shaped to fit themolding 22 on the panel and to permit the forcing of the clip up overthis molding. Thin spacer blocks 29 are introduced between the panel 7and the web 3 to hold the parts rigidly and at a determined slightdistance apart. 0r the spacers may be omitted and the clips proportionedso as to clamp the plate 7 against the webs 3, as shown for example inFigs. 5 and 6. And, in general, the variations shown in detail in eachof the several figures are applicable to the styles of casing shown ineach of the other figures.

It will be observed that the transverse fins 2 of the radiatingstructure form alternately flues which are closed by the outer webs 3and channels which are closed on three sides, but open on the outerside. lVhen the casing is applied, the front panel thereof substantiallyor approximately covers the outer sides of these channels and convertsthem into flues closed in cross-section. Such flues have an importantfunction in securing a very rapid heating and circulating effect by theinduced draft of the heated air.

wWhether the lradiator be suspended above the floor or supportedthereon, the casing should haveits lower edge clear the floor or haveopenings at or near the bottom for admitting air to the lower ends ofthe radiator flues Aand channels. The invention may be applied yalso toradiators supported by legs resting on the floor. And, however theradiator is supported, the pipes may pass through the floor and directlyupward to the valves.

i The slots in the end walls may be of various other shapes than thatshown. For example, they may extend horizontally inward from the'edgeand then upward.

Various other modifications may be made by those skilled in the artwithout departing from the invention as deiined in the following claims.
